DETAILED DESCRIPTION

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] like Figure 1 and Figure 2 As shown, a novel skin wound support frame comprises a frame body 1 and a fixed plate 11, a sliding rod 2 is arranged between the inner two sides of the frame body 1, and a screw rod 3 is passed through the bearing at the right opening of the frame body 1, a screw rod 3 is connected to the outside of the screw rod 3, and both sides of the screw rod nut 5 are connected to movable plates 6, the rear end of the movable plate 6 is rotatably connected to a clamping roller 7, and the front end of the movable plate 6 is connected to a swing arm 8 through a rotating shaft, and the other end of the swing arm 8 is respectively connected to a support rod 9 and a swing arm 2 10 through a rotating shaft, the fixed plate 11 is fixed to both sides of the frame body 1, and the rear end of the fixed plate 11 is rotatably connected to a clamping roller 2 12, two sliding rods 2 and movable plate 6 are respectively arranged, and the sliding rod 2 and movable plate 6 are slidably connected, the sliding rod 2 and the screw rod 3 are parallel to each other, two swing arms 1 8, two support rods 9 and two swing arms 10 are respectively arranged, and the end of the swing arm 2 10 away from the support rod 9 is rotatably connected to the frame body 1 through a rotating shaft.

[0024] The specific operation is as follows: the hand rubbing wheel 401 is manually driven to rotate, causing the screw nut 5 to make a lateral displacement outside the screw 3 to adjust the distance between the movable plate 6 and the fixed plate 11, so that the clamping roller 1 7 and the clamping roller 2 12 are distributed on both sides of the patient's limb, and the clamping force of the clamping roller 1 7 and the clamping roller 2 12 is used to fix the frame 1 on the patient's limb where the skin is injured, so as to prevent the frame 1 from tipping over or deviating from the skin injury when the patient shakes his body, affecting the use effect.

[0025] like Figure 3 and Figure 4 As shown, a limiting assembly 4 is sleeved on the outer right side of the screw rod 3, and the limiting assembly 4 includes a hand rubbing wheel 401 and a return spring 402, and the return spring 402 is connected to the groove on the surface of the hand rubbing wheel 401, the limiting assembly 4 also includes a pawl 403 and a ratchet 404, and the end of the return spring 402 away from the hand rubbing wheel 401 is connected to the pawl 403, the ratchet 404 is fixed to the right side of the frame 1, the pawl 403 and the hand rubbing wheel 401 are rotatably connected, the hand rubbing wheel 401 and the ratchet 404 are coaxially arranged, the end of the screw rod 3 away from the hand rubbing wheel 401 is rotatably connected to the frame 1, and the frame 1 has a concave structure.

[0026] The specific operation is as follows: when the hand rubbing wheel 401 is released, under the action of the elastic force of the reset spring 402, the pawl 403 at the groove on the surface of the hand rubbing wheel 401 will rotate and keep in engagement with the ratchet 404, thereby preventing the lateral displacement of the screw nut 5 caused by the rotation of the hand rubbing wheel 401 and the bidirectional screw 901.

[0027] In summary, when the novel skin wound support frame is used, the distance between the clamping roller 1 7 and the clamping roller 2 12 is first adjusted according to the thickness of the limb with wound on the skin surface of the patient, that is, the ratchet 403 is pressed to deform the reset spring 402, and the ratchet 403 is retracted into the groove on the surface of the hand-rubbing wheel 401, and then the hand-rubbing wheel 401 is manually screwed, so that the screw nut 5 drives the moving plate 6 to move horizontally to the left about the outside of the screw 3, until the clamping roller 1 7 and the clamping roller 2 12 clamp the patient's limb, so that when the patient shakes his body, the frame 1 is not easy to fall over or deviate from the skin wound, thereby ensuring the use effect;

[0028] Since the moving plate 6 follows the movement of the screw nut 5 and slides about the outside of the slide bar 2, the swing arm 1 8 and the swing arm 2 10 rotate to move the support rod 9 away from the frame 1, thereby increasing the distance between the two support rods 9, so that the frame 1 can support the patient's clothes or quilt in a larger range, thereby isolating and protecting the affected area;

[0029] When the hand-rubbing wheel 401 is released, the pawl 403 at the groove on the surface of the hand-rubbing wheel 401 will rotate under the action of the elastic force of the return spring 402 and keep engaging with the ratchet wheel 404, thereby preventing the screw nut 5 from being laterally displaced due to the rotation of the hand-rubbing wheel 401 and the bidirectional screw 901;

[0030] Through the coordinated use of the above structures, the problem that the existing support frame does not have a convenient adjustment function and needs to use tools to tighten the locking screws one by one to achieve distance adjustment between the supports is solved.

[0031] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
